Recent work on the problem of detecting synonymy through corpus analysis has used the Test of English as a Foreign Language (TOEFL) as a benchmark. However , this test involves as few as 80 questions , prompting questions regarding the statistical significance of reported results. We overcome this limitation by generating a TOEFL-like test using WordNet,… (More)

Human and animal studies have implicated brain-derived neurotrophic factor (BDNF) in the etiology of psychiatric disorders. It is expressed in limbic regions of the brain associated with the regulation of emotionality during fetal development and in the adult animal. To further our understanding of the role of BDNF in the modulation of mood and to… (More)

Environmental enrichment attenuates the response to psychostimulants and has been shown to reduce both anxiety and stress-related behaviors. Since stress is a major vulnerability factor for addiction, we investigated whether enrichment could reverse stress profiles in high anxious rats as well as reduce their amphetamine sensitivity. Using selectively-bred… (More)

Eosinophils are a major component of the inflammatory response in persistent airway inflammation in asthma. The factors that determine the retention of eosinophils in the airway remain poorly understood. Elevated levels of fibronectin have been observed in the airway of patients with asthma, and the levels correlate with eosinophil numbers. To determine if… (More)

The use of narcotics by adolescent females is a growing problem, yet very little is known about the long-term consequences for either the user or her future offspring. In the current study, we utilized an animal model to examine the transgenerational consequences of opiate exposure occurring during this sensitive period. Female rats were exposed to… (More)

Tandospirone is an azaspirodecanedione derivative under investigation as an antidepressant. Metabolism of tandospirone in humans and rodents leads to 1-(2-pyrimidinyl)-piperazine (1-PP), presumed to have pharmacologic activity. To determine the relative contributions of tandospirone and 1-PP after tandospirone administration, we evaluated open-field… (More)

BACKGROUND & AIMS
Fatty Acid Transport Protein 5 (FATP5) is a liver-specific member of the FATP/Slc27 family, which has been shown to exhibit both fatty acid transport and bile acid-CoA ligase activity in vitro. Here, we investigate its role in bile acid metabolism and body weight homeostasis in vivo by using a novel FATP5 knockout mouse model.

Pregnant mice were treated with cocaine, 10 mg/kg/day, during days 13 to 20 of gestation. Cocaine sensitization and dopamine transporter binding were evaluated in offspring at 6 weeks of age. Sensitization, defined as the increase in activity after 5 injections of cocaine compared to 1 injection, was reduced in cocaine-exposed mice. Dopamine transporter… (More)

There is much speculation regarding the effects of estrogen withdrawal at the end of pregnancy on forebrain dopamine, however, few studies have directly examine changes in this system postpartum. The present work sought to determine what changes in forebrain dopamine function occur in the postpartum rat. Specifically, prepulse inhibition of the acoustic… (More)
